In recent years, the use of the electrical control cabinet is more and more frequent, long-term use of the electrical control cabinet needs us to clean and maintain, so as to ensure the use of the cabinet, then how do we clean the clean surface of the electrical control cabinet?
In the electrical control cabinet after the production and molding is not really completed, it needs to be alkaline washing, certainly many people will have questions, why to alkaline washing it?
There is a lot of oil on the surface of the electrical control cabinet, so we have to clean it. The last step is to clean it. Alkali lotion is made up of Na2C03 Na3P04 Na2Si03 and additives. Wash with alkali solution washed with clean water to scrub, the purpose is to wipe off the residue of alkali solution.
The oxide film naturally formed on the surface of the electrical control cabinet shell is generally non-uniform and non-continuous film, which must be thoroughly cleaned in advance when painting the surface. For die-casting parts, nitric acid can be used to conduct oxide film treatment on the surface. After removing the oxide film, we still need to carry out further treatment with clean water.
